Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X275-10
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X275-10 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 275mm stroke, G1/2 air ports and adjustable end cushioning. Its no-tie-rod, hard-anodized profile barrel is more compact than an ISO 15552 cylinder of the same bore — a space-saver on tight machines.

About the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X275-10
The extruded hard-anodized aluminium barrel leaves out external rods, making the body shorter and more compact than a same-bore ISO 15552 unit.
A 10 mm external adjuster lets you shorten the extend stroke on site from the 275 mm maximum down to 265 mm, fine-tuning the end position without swapping the cylinder. The retract end remains fixed. Air connects via a G1/2 port, and adjustable 33 mm cushions decelerate the payload at both ends. Note this SKU lacks a magnet and cannot take a sensor; you would need the -S version for CMSE or DMSE switches.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 N |
| 0.7 MPa | 4935 N | 4935 N |
| Max (@1.0 MPa) | 719 kgf | |
JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X275-10 Is Used
Press Fit Tuning
Dial in the exact seating depth of a bearing press by trimming the extend stroke up to 10 mm on site, ensuring perfect insertion without re-engineering the fixture.
Pallet Stop Adjustment
Fine-tune the retract stop position for varying pallet widths on a heavy-duty conveyor line, using the fixed retract end and adjustable extend limit to set the dwell distance.
Vertical Lift Dampening
Lift a 200 kg materials rack vertically while relying on the 33 mm adjustable air cushions to decelerate the load smoothly at the stroke extremes.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X275-10 the Right Cylinder?
When sizing this 100 mm bore model, compare it against the 80 mm bore if your load is lighter, or step up to the 125 mm bore if you need more power. The 10 mm adjustable window is ideal for sharing a spare cylinder across slightly different stroke variants or dialing in a final end position on the machine. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this is a 275 mm stroke, ensure you guide the load to prevent side-load damage to the rod seal. Without a -S suffix, this cylinder cannot accept magnetic sensors.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X275-10 FAQ
This 100 mm bore cylinder pushes with 3927 N and pulls with 3574 N at 0.5 MPa. At 0.7 MPa it pushes 5497 N and pulls 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 air port and features a 32 mm piston rod with an M26x1.5 thread.
The external adjuster lets you shorten the extend stroke on site by up to 10 mm, giving a usable extend range of 265 to 275 mm. The nominal 275 mm stroke is the maximum, and the retract end is fixed. This mechanism only sets the end position; it does not lock the load. If air is lost, the cylinder drifts, so you need an external rod lock or pilot-operated check valve for load holding.
